WHEEL BAIL-CLAMP.

T o all whom it may' concern Be it known that I, WILLIAM BoD'rrE, acitizen of the United States, residing at Empire, Canal Zone, haveinvented new and useful Improvements in lVheel Rail-Clamps, of which thefollowing is a specification.l

The present invention relates to a new and improved stay which may beused -in the nature of a chock for 'holding either a car, excavator,derrick or the like against movement on the rails of a track, andtheimprovement resides 4in the construction, combination and operativearrangeinentof parts set forth inthe following description and fallingwithin the scope of 'the'appended claims.

In the drawings: Figure l is a perspecf tive view of a wheel chockembodying my improvement as secured in posit-ion on a rail,-F,ig. '2 isa .view in side elevation of Y my improvement, Fig. 3 is atransverse'scc- V'tional view upon theline 3-3 of Fig. 2,

1`Fig. 4 is a. horizontal' sectional vview upon vthe line L -4 of Fig.3. `In the Ause of machines such as excavators, 'derricks and the like,adapted' tolle oper-VA ated and moved from place toplace on rails',- itis necessary that the movement-.of the machine along the .rails beprevented when t! is desired to operate the machine in any fixedposition. The force tending to move the machine along the rails isgreat, especially where the power of the machine is exerted lengthwiseof the track, as for example, in the operation of a scraper bucketexcavator, when the bucket is drawn toward the machine on a liuclsubstantially parallel with the track.- It is, therefore, necessary thatdevices used to hold the machine in a tixed position upon the rails bestrorg and effective, and at the same time ready reinoval or adjustmentof position may be obtained without loss of timel or labor. It is' alsodesirable to provide such a chock with means whereby the saine may bepar-A tially disengaged from thc truck in order to permit of the saidchock being slid by the wheels of the machine to which it is attai-lied,a certain and desired distance when the machine isto bc brought from onepoint to another without. necessitating the operator of the machineleaving his position upon the machine."

I accomplish tlie'above-nained desired purpose through the medium of theapparatas, and its operative applica-tion illus- Specification, ofLetters Patent. Application tiled January 21, 1918. Serial No. 743,359.

proved chock or stay and 2 the track tl-`IV which thestay is attached.The chock embodies essentially. a pair of side membersfor wings, lwhichare designated by the'numer--- als 3 and 4 respectively.A Both oftliesef-A wings embody fiat-metallic members eachv being of a sutiicientstrength to etectively withstand the strain to which it is sub. jected.As shown in the drawings, each of the wings ,and 4 preferably comprisesa fiat member, and each of the said members has its upper and inneredge'preferably integrally formed with longitudinally extending lugs 5.the same being preferably three in number and one larranged centrally ofthe member 3 and the remaining pair arranged to the opposite sides ofthe member 4 and disposed adjacent the opposite ends of the lug upon themember Secured upon one of the lugs -5 of the member 4' and arrangedupon tlieupper face thereof is a. projecting eye 7, and `the member 3directly belowdtsJrig 5 is integrally VAformed with a lutcrall"extendingtongue 8 -which extends througllanelongated angularly arranged' iopening 10, the saidopening heilig adaptedv to receive a wedge member 1LA Arranged to the lower longitudinal edges of each of` the members 3 andtand upon the inner face thereof are ribs -12 and 13 respectively,whilc'disposed at a distance above the said ribs equal to Vthe thicknessof'the heads of the rails are second rib members' 14 and 15respectively. These' ribs are, of course, of a lesser thickness than thelugs' 5, and each of the said lugs has its innerface rounded and bearingagainstI the inncr face of the adjacent wing or plate to permit of thelower portions of the Said plates bcin'g readily swung toward each`other when the wedge ll is inserted through the opening tl of thc tongueS. and. if desired, the faces ot' thc ings between the ribs l2 alid l-land li and l5 rcs|urctivelyll may be iougliencd to engage with theopposite faces of the heads of the rails, and thus serve asan additionalmeans for preventing the longitudinal iiiovcnientof the chock whenconnected with the rails. .Uso if desired, the lugs may be provided withlongitudinal openings for the reception of a pintle a. whereby the wingsmay liingedly connected. f

One of the transverse edges of the wing be lilo I i? A member 4 1s or acurved 0r arcuate shape, as

designated by the numeral 16, as is also the end 17 of the section 3which is arranged upon this side of the chock, the said curvaturecorresponding with the car'fwheel with which the chock engais'heretofore stated, 1t 1s desirable that.

u the chock remain a permanent attachment' which has v the wedge member11 is an additional flexi-` ble element5l9Lf-3It will be noted that byexerting a ulliupon the element 19, thewedge mem er Il will be partiallywithdrawn from its engagement with the tongue. 8, Aandas the chock isthus broughtout of tight frictional engagement with the rail, a movemento-the wheel which contacts with the chock will slide the same along therail. The wedge may be provided with a removable stop pin b' whichwillprevent the entire withdrawal of the Wedge and thewedge may be ofsufficient weight `into locking position when leased.'

From the a5 to gravitate the cham is referegoing description, taken indrawings, the simplicity lof the device, as well as the advantagesthereof, will it is thought -be perfectly apparent to those skilledinthe art to which such inventions appertain.

Having thus described the invention, what I claim is:

. 1. A wheel chock comprising a chock member embodyingr separate wingshaving their inner faces adjacent their upper ed es provided withabutting lugs, the wings ie-1 ing provided with rail receiving passagesdisposed below the lugs, and a removable the peripheryA of .wedge membercooperating with an element provided upon one of the 'wing members andadapted to frictionally engage with the side of the second'wing member.

2. A wheel chock comprising a chock member, a' pair of fiat wing membershaving their inner faces provided with inturned Mspect'ive wing members,each of the wings having its inner face provided with spacedvlongitudinally extending ribs forming rail engaging passages,A andagravity wedge member `co-acting vwith' an element upon one f tionallycontact withv the outer face of the second Wing member.

3. A wheel chockz-.comprisin member constructed of a pair o havingco-acting fulcrum members, said .win'gs being provided with railpassages, one of the Wings having a tongue which is adapted to extendthrough 'an opening in the second wing, and a Agravity wedge engagingthe. tongue and frictionallyv contacting with the outer face of one of.the wing members.

a chocld constructed of a pair of hinged wings, the said wings beingprovided with rail receivf ing passages disposedbelow their hinge, oneof the Wings having an angular tongue which projects through 'an openingin the lsecond wing, said tongue being provided with an inclined slot, agravity wedge arranged within the inclined slot .ing with the outer faceof one of the wings of the chock and a flexible element for the gravitywedge.
